Community Oral Health Test Preparation
Course Introduction
Community Oral Health focuses on the principles and practices involved in promoting oral health and preventing dental diseases at the population level. The course covers key topics such as epidemiology of oral diseases, social determinants of oral health, public health policies, community-based oral health programs, and preventive strategies including water fluoridation and oral health education. Students learn how to design, implement, and evaluate oral health initiatives tailored to diverse communities, and develop the skills necessary to advocate for public health improvements. Emphasis is placed on interdisciplinary collaboration, outreach techniques, and evidence-based approaches to address disparities and improve oral health outcomes on a broader scale.
